I think the filtering in pgoutput ought to make use of
is_publishable_class() in some way.  That takes care of non-tables such
as materialized views, but it also filters out the information_schema
tables for example.  Right now, if you insert something into one of the
IS tables, it gets shipped over the wire but is then dropped by the
apply because there is no pg_subscription_rel entry of the table.  That
doesn't quite have the user-visible effect as this bug, but it's bogus
nonetheless.

So I propose this alternative patch that covers all these cases.
